Self-Cleaning Nanocoatings for Building Surfaces: A Comprehensive Review of Materials and Methods.

This comprehensive review examines the current state of self-cleaning nanocoatings for building surfaces. Nanocoatings are a form of nano-structured materials that contain active components, such as photocatalysts, that provide superior self-cleaning properties when exposed to light. This review discusses the various materials and methods used in the development of selfcleaning nanocoatings, including titanium dioxide, zinc oxide, and other metal oxide. The properties of these materials, such as photocatalytic activity, durability, and water repellency are described in detail. The review also provides a comprehensive overview of the preparation methods for nanocoatings, including physical vapor deposition, chemical vapor deposition, and sol-gel processing. Finally, the review concludes with a discussion of the potential applications of self-cleaning nanocoatings for building surfaces, such as reducing maintenance costs, improving aesthetics, and increasing energy efficiency.
